About .pkm Files
PKM files are used to store session data for the PockEmul emulator. They are saved as binary data under the MIME type application/octet-stream.
These files hold the session state so that an emulator session can be resumed later. They are not meant to be edited directly by users and must be handled by the PockEmul software.
- Data Container: The binary format (octet-stream) means the file holds non-text data.
- Emulation Sessions: It records the state of a PockEmul session.
- Software Specific: Only PockEmul or compatible emulators can properly read and use this file.
According to FilExt.com, PKM files are application-specific files that require the correct emulator software to work as intended.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .pkm file?
A .pkm file serves as a session data container for the PockEmul software, an emulator for vintage pocket computers. It stores the exact state of the device's memory and current session, allowing users to save their progress and resume exactly where they left off.
How do I open a .pkm file?
You must use the PockEmul application to open this file type. It is not a standalone document; instead, you should launch PockEmul and use the internal "Load" or "Import" function to bring the session data into the emulator.
Can I edit a .pkm file with a text editor?
No, you should not attempt to edit this file manually. Because it is saved as binary data (often identified as application/octet-stream), opening it in a text editor like Notepad will display unreadable garbage characters, and saving changes will likely corrupt the file.
Why is my .pkm file not opening in PockEmul?
This issue usually occurs if the file is corrupted or created by an incompatible version of the emulator. Additionally, verify that the file is actually a PockEmul session; the .pkm extension is sometimes used by other software, such as Pokémon save editors (PKHeX), which are not compatible with PockEmul.
How do I convert a .pkm file to text?
You cannot convert the .pkm file directly because it contains complex machine state data. To extract code or text, you must open the session inside PockEmul first and use the application's export features to save the program listing or screen output as a standard text file.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
